What the gurus are saying
The fragrance is a dealbreaker for some: dermatologists have described it as 'headache inducing' and 'very heavy,' which reviewers note can cause pilling when layered under sunscreen. Others find the visible brightening benefits worth tolerating, the 10% niacinamide paired with phenylethyl resorcinol reduces hyperpigmentation and dark spots, leaving skin more even-toned, though the higher concentration may irritate those sensitive to niacinamide.
